Description

Economical Stereo Imaging Projector

Technical field:

The utility model belongs to projection equipment, in particular to an economical stereoscopic imaging projector.

Background technique:

Usually when we use a monitor to watch stereoscopic images, when the refresh rate is lower than 60HZ, we will feel that the images on the screen are flickering. This is because the images in the display are output alternately by two images, so that in fact only half of the output refresh rate of the display can be achieved. The stereoscopic glasses are synchronized with the computer, even if the projector has a high refresh rate, it is useless, and the high-refresh images cannot reach the projector at all. Such frequently flickering images will cause fatigue to the eyes of the viewer.

Invention content:

The purpose of this utility model is to overcome the shortcomings in the above-mentioned prior art, and provide an economical three-dimensional imaging projector, which has clear images, high resolution, and reliable performance, and will not cause fatigue when watching for a long time .

The technical scheme of the utility model is: an economical three-dimensional image projector, including a box, characterized in that: the box is equipped with two ordinary projectors, two parallel shafts and an inclination adjustment mechanism; the inclination adjustment mechanism consists of a fixed clip , an inclination adjustment knob, a flexible shaft and a flexible shaft connector; the inclination adjustment knob and the flexible shaft connector on the fixing clip are installed on the flexible shaft; turning the inclination adjustment knob drives the flexible shaft to rotate, and one end of the flexible shaft is threaded, Clamp the flexible shaft connection head to cooperate; the two parallel rotating shafts are positioned through the left and right rotating shaft side plates, and the two projectors are fixed by the fixing clips that can rotate around the rotating shafts.

Above-mentioned flexible shaft is the flexible steel wire that has screw thread at one end.

The above-mentioned left and right rotating shaft side plates have two pairs of parts equipped with sliding bearings and the center distances between the two pairs of holes are equal.

The utility model has the following advantages and positive effects:

1. It is suitable for graphics workstations and ordinary computers.

2. The video signal of the computer can be converted into two channels of RGB signals and output to two DLP projectors to produce 3D images.

3. The image is clear, the resolution is 1280×1024; the refresh rate is 85HZ.

4. Reliable performance and easy operation.

5. Watching for a long time will not cause fatigue.

6. Low cost, high quality 3D images.

7. It has all the features and functions of a VR (Virtual Reality) production environment.

8. Wide adaptability. Such as: virtual reality demonstration (stereoscopic projection virtual simulation digital city, virtual reality laboratory, simulated driving), 3D games, stereoscopic movies, etc.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

Detailed ways:

As shown in the figure: an economical three-dimensional imaging projector, two projectors 2, a rotating shaft 3 and an inclination adjustment mechanism are installed in a box body 1. The inclination adjustment mechanism is composed of a fixed clip 4, an inclination adjustment knob 5, a flexible shaft 6 and a flexible shaft connector 7; the flexible shaft connects the inclination adjustment knob with the flexible shaft connector on the fixed clip. Turn the adjustment knob to drive the flexible shaft to rotate. One end of the flexible shaft is threaded, and it cooperates with the flexible shaft connector on the fixing clip to realize the up and down movement of the fixing clip. The two projectors are fixed by the fixing clip that can rotate around the rotating shaft. The two parallel rotating shafts positioned by the right two rotating shaft side plates 8 strictly ensure the horizontal coincidence of the images projected by the projector. Due to the flexible shaft connection, the projection inclination angle of the two projectors can be adjusted easily and accurately through the inclination adjustment knob. Above-mentioned rotating shaft side plate has two pairs of sliding bearings 9 and two pairs of parts with equal hole center distance. The flexible shaft is a flexible steel wire with a thread at one end. The purpose of using the flexible shaft connection is to eliminate the horizontal and vertical displacements caused by the rotation of the projector relative to the rotating shaft during the rotation of the projector, as well as the position error generated during installation. If a rigid shaft is used, it will cause stagnation, so a flexible shaft is used.

The utility model adopts the polarized light technology, transmits the video signal of the VCT or PC to the DLP/LCD projector, and projects 3D images on the large screen. The left and right eyes watch two different images at the same time through the angle of polarization. Image output is not limited by the refresh rate. The left and right eyes see two simultaneous output uninterrupted images, which is the same as our daily habit of viewing images, without flickering, and completely eliminates the fatigue caused by flickering. It can make the audience blend into the digital environment and have an immersive and real feeling. Cooperate with data gloves, space tracking locators, joysticks, etc., to achieve the effect of human-computer interaction.
